Building Docker image with Packer and provisioning with Ansible

Overview

Packer

• Packer is used to build image from a base image, perform provisions and store (commit) the final image.

• We use provisioners and Packer templates to do the actual work to create the final image.

• We use Ansible for provisioning.

The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale "en_US.UTF8".
The default database encoding has accordingly been set to "UTF8".
